Stockholm has an extensive network of metros, commuter trains, buses and trams that are operated by the Storstockholms Lokaltrafik.
The metro or tunnelbana is the heart of the system with trains running daily from 5am till 1am and even later at the weekends. The metro is linked with the commuter train service which, however, is not that frequent.
